Long-term outcome after en bloc resection and reconstruction of the spinal column and posterior chest wall in the treatment of malignant tumors. J Orthop Sci 2022; 27:899-905. [PMID: 34030940 DOI: 10.1016/j.jos.2021.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 02/21/2021] [Accepted: 03/31/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND Malignant tumors occurring around both the spinal column and posterior chest wall are uncommon. Surgical resection of chest wall tumors adjacent to the spinal column is still challenging due to the surrounding anatomical structures. The purpose of the present study was to evaluate the long-term outcomes of surgical management in malignant tumors involving the spinal column and posterior chest wall. METHODS Between 1999 and 2007, 10 consecutive patients underwent en bloc resection combined with the posterior chest wall in the treatment of malignant tumors around the spinal column. There were 6 males and 4 females with a mean age at the surgery of 40.9 years old (range, 14-62 years old). The mean postoperative follow-up period was 159.7 months (range, 84-245 months). The clinical history, physical examination, laboratory data, radiological findings, and operative findings for each patient were retrospectively reviewed. RESULTS All surgeries were performed via a combined anterior and posterior approach. The mean numbers of partially resected vertebrae and ribs were 3.1 and 4.1, respectively. Lower or upper lobectomy was performed in four patients, and the diaphragm was partially resected in two patients. The surgical margin was wide in seven patients and marginal in two patients. Although five patients had postoperative respiratory problem, all patients improved immediately without life-threatening complications. There were no patients with respiratory insufficiency after surgery. One patient with osteosarcoma died of lung metastases 99 months after surgery. At the final follow-up, only one patient had local recurrence, five had been continuously disease-free, and three were alive with no evidence of disease. CONCLUSIONS En bloc resection and reconstruction in selected patients with malignant tumors involving both the spinal column and posterior chest wall demonstrated good long-term results for local control and the respiratory function.

Abstract
Background Lung cancer with related pericardial effusion is not rare. Intervention is a crucial step for symptomatic effusion. It is unknown, however, whether the different invasive interventions for pericardial effusion result in different survival outcomes. This study analyzed the clinical characteristics and prognostic factors for patients with non-small-cell lung cancer (NSCLC) who have undergone different procedures. Methods From January 2006 to June 2018, we collected data from patients with NSCLC who have received invasive intervention for pericardial effusions. The patients were divided into three categories: simple pericardiocentesis, balloon pericardiotomy, and surgical pericardiectomy. Kaplan–Meier curve and log-rank test were used to analyze the pericardial effusion recurrence-free survival (RFS) and overall survival (OS). Results A total of 244 patients were enrolled. Adenocarcinoma (83.6%) was the major NSCLC subtype. Invasive intervention, including simple pericardiocentesis, balloon pericardiotomy, and surgical pericardiectomy, had been carried out on 52, 170, and 22 patients, respectively. The 1-year RFS rates in simple pericardiocentesis, balloon pericardiotomy, and surgical pericardiectomy were 19.2%, 31.2%, and 31.8%, respectively (P = 0.128), and the median RFS was 1.67, 5.03, and 8.32 months, respectively (P = 0.008). There was no significant difference in OS, however, with the median OS at 1.67, 6.43, and 8.32 months, respectively (P = 0.064). According to the multivariable analysis, the gravity in pericardial fluid analysis, receiving systemic therapy after pericardial effusion, and the time period from stage IV lung cancer to the presence of pericardial effusion were independent prognostic factors for pericardial effusion RFS and OS. Conclusions Patients who have undergone simple pericardiocentesis alone for the management of NSCLC-related pericardial effusion have lower 1-year RFS rates than those who have undergone balloon pericardiotomy and surgical pericardiectomy. Therefore, balloon pericardiotomy and surgical pericardiectomy should be carried out for patients with NSCLC-related pericardial effusion if tolerable. This is the first study to compare the three common procedures to manage NSCLC-related pericardial effusion. Simple pericardiocentesis group had lower 1-year RFS rate than balloon pericardiotomy or surgical pericardiectomy group. Surgical pericardiectomy as management demonstrated an improving OS trend.

Proposal for Rib invasion as an independent T descriptor for non-small cell lung cancer: A propensity-score matching analysis. Lung Cancer 2021; 159:27-33. [PMID: 34304050 DOI: 10.1016/j.lungcan.2021.07.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Revised: 06/21/2021] [Accepted: 07/14/2021] [Indexed: 01/16/2023]
Abstract
INTRODUCTION To evaluate the prognosis between patients with non-small cell lung cancer (NSCLC) invading difference depth of chest wall and estimate the impact of rib invasion on the pathological T classifications (pT). METHODS We retrospectively evaluated 521 patients with resected pT3-4 NSCLC. Propensity-score matching (PSM) balanced the known confounders of the prognosis, resulting in two sets (rib invasion vs the pT3 and pT4 group). Recurrence-free survival (RFS) and Overall survival (OS) was assessed by Cox regression and Kaplan-Meier methods. Time-dependent receiver operating characteristic (ROC) curves were used to assess the additional benefit for survival prediction after reclassifying rib invasion cases. RESULTS Chest wall invasion occurred in 171 patients (62 rib invasion, 51 parietal pleural invasion [PL3] and 58 soft tissue invasion). Rib invasion was found to be an independent prognostic factor for both RFS (p = 0.006) and OS (p < 0.001) of pT3-4 NSCLC. The survival of rib invasion group was the worst (RFS: 13.1%; OS: 19.8%), followed by PL3 (RFS: 34.2%, P = 0.001; OS: 48.8%; p < 0.001) and the soft tissue invasion group (RFS: 40.6%, p = 0.001; OS: 57.7%, p < 0.001). Besides, the prognosis of rib invasion group was also found to be worse than those of pT3 (RFS: p < 0.001; OS: p < 0.001) and pT4 group (RFS: p = 0.002; OS: p < 0.001). After PSM, the 5-year RFS rate of rib invasion group were still lower than that of pT3 and pT4 group (p < 0.001); the 5-year OS rate of rib invasion was similar with that of pT4 group (p = 0.066) but lower than that of pT3 group (p = 0.014). The time-dependent ROC curves demonstrated that reclassifying rib invasion as pT4 disease provided an additional benefit for survival prediction (p < 0.001). CONCLUSION The rib invasion group had a worse prognosis than the PL3 and pT3 groups. The prognostic impact of rib invasion should be further validated as a pT4 disease in the TNM classification.

Abstract
A diaphragmatic tumor is usually caused by metastasis from lung cancer, malignant mesothelioma, and malignant thymoma. Endometrial cancer is rarely involved in metastasis to the diaphragm. A right anterior mediastinal tumor was found in a 60-year-old woman who was initially diagnosed with endometrial carcinoma. There was initially no relationship between the right anterior mediastinal tumor and endometrial carcinoma. Radical curative surgery was performed for endometrial carcinoma. The endometrial carcinoma stage was IA. The patient was admitted to the Department of Thoracic Surgery 6 months after the curative surgery. Intraoperative exploration showed a tumor growing in the right diaphragm. Right diaphragmotomy was performed. Immunohistochemistry showed metastasis of endometrial carcinoma to the diaphragm. Endometrial cancer solitary metastasis to the diaphragm is rare. Clinicians should be aware of this possibility. Surgical treatment followed by a pathological examination is the most useful method for determining the diagnosis of a diaphragmatic tumor due to metastasis of endometrial cancer.

Abstract
Background Surgical outcomes of pneumonectomy for lung cancer differ based on various therapeutic strategies. Methods One hundred and fifty-one patients who underwent pneumonectomy were divided into three groups based on patients' therapeutic conditions: a primary pneumonectomy group (no preoperative treatment, n=137), an induction group (planned surgery after induction chemotherapy or chemoradiotherapy, n=10), and a salvage group (surgery for residual or enlarged lesions after radical non-operative therapies, n=4). Results Multivariate analysis showed that completeness of resection (P=0.003), subcategorization of whether there was no invasion, infiltration only to the main bronchus or pleura, or invasion of other deeper structures (P=0.008), and the presence or absence of mediastinal lymph node metastasis (P=0.033) were significant prognostic factors. Severe postoperative complications occurred in 5.1% (7/137), 20% (2/10), and 0% (0/4) in the primary pneumonectomy, induction, and salvage groups, respectively. Among patients with pN0-1 disease, the 3-year overall survival rate was 58.7% in the primary pneumonectomy group, 100% and 40% in cases with high and low pathological effects in the induction group, respectively, and 50% in the salvage group. Among patients with pN2 disease, this rate was 41.4% in the primary pneumonectomy group, and no patients survived for postoperative 2 years in the other groups. Conclusions For patients undergoing pneumonectomy, subcategorization based on the invasion status (none/bronchus/pleura or other deeper structures) is a crucial prognostic factor. To consider pneumonectomy in the induction or salvage setting, selecting patients with pN0-1 disease may be mandatory.

Abstract
PURPOSE OF REVIEW Pericardial effusion is commonly associated with malignancy. The goals of treatment should include optimizing symptom relief, minimizing repeat interventions, and restoring as much functional status as possible. RECENT FINDINGS Pericardiocentesis should be the first intervention but has high recurrence rates (30-60%). For patients with recurrence, repeat pericardiocentesis is indicated in those with limited expected lifespans. Extended pericardial drainage decreases recurrence to 10-20%. The addition of sclerosing agents decreases recurrence slightly but creates significant pain and can lead to pericardial constriction and therefore has fallen out of favor. Most patients with symptomatic pericardial disease have a short median survival time due to their underlying disease. In patients with a longer life expectancy, surgical drainage offers the lowest recurrence rate. Surgical approach is based on effusion location and clinical condition. Subxiphoid and thoracoscopic approaches lead to similar outcomes. Thoracotomy should be avoided as it increases morbidity without improving outcomes.

Abstract
OBJECTIVES The eighth tumor-node-metastasis (TNM) classification system for lung cancer has been used since January 2017 and must be applied to an individual institution's database. METHODS We analyzed pathological stage data of 2756 patients who underwent resection of non-small-cell lung cancer, particularly in terms of the degree of visceral pleural invasion and involved neighboring structures. RESULTS Few patients had stage IIA disease (103, 4%); stratification between stages IB and IIA was insufficient (p = 0.129). When T2a tumors were divided into PL1 and PL2 subgroups based on the degree of pleural invasion, there was a significant prognostic difference between the subgroups (p < 0.001). By incorporating T2a tumors with PL2 (T2a-PL2) into the T2b category, modified stages IB, IIA (234, 8%), and IIB were well stratified (IB vs. IIA, p < 0.001; IIA vs. IIB, p = 0.011). Focusing on T3 tumors with PL3 (T3-PL3) invading neighboring structures, multivariate analysis for surveying pT3N0-2M0 tumors revealed that completeness of resection (p = 0.002), implementation of any postoperative therapies (p = 0.003), and subcategorization of whether only the pleura was infiltrated or other deeper structures were also invaded (p = 0.024) were significant and crucial predictors. N2 disease showed worse outcome than N0-1 diseases, with marginal difference (p = 0.054). CONCLUSION T2a-PL2 tumors could be categorized into a worse prognostic T2b category. For T3-PL3 tumors involving resectable neighboring organs, subcategorization of whether there is only pleura infiltration (T3a) or other deeper structure invasion (T3b) could be a practical consideration.

Abstract
BACKGROUND This study determined the characteristics and prognosis of each descriptor of T3 non-small cell lung cancer (NSCLC). METHODS A total of 3,241 patients underwent an operation for NSCLC between 2001 and 2013, and this study included 461 patients who received complete anatomic resection of T3 NSCLC. The T3 descriptors were coded as follows: tumor invading main bronchus within 2 cm of the carina (T3-cent), tumor invading beyond visceral pleura (T3-inv), tumor larger than 7 cm (T3-size), separate tumor nodules (T3-sep), or tumor with combined T3 descriptors (T3-comb). RESULTS The T3 distribution was as follows: T3-cent, 75 patients (16.3%); T3-inv, 157 patients (34.1%); T3-size, 132 patients (28.6%); T3-sep, 34 patients (7.4%); and T3-comb, 63 patients (13.7%). Subgroup analyses revealed a significant survival benefit in the T3-cent group compared with the other groups (all p < 0.05). The 5-year disease-free survival (DFS) values were 55.4%, 36.7%, 40.9%, 30.3%, and 32.0% in the T3-cent, T3-inv, T3-size, T3-sep, and T3-comb subgroups, respectively. Multivariable analyses revealed that age (p = 0.019), N status (p = 0.001), adjuvant chemotherapy (p < 0.001), and T3 descriptors (T3-cent versus others, p < 0.001) were the most important independent prognostic factors for DFS. Additional analyses were performed to evaluate prognostic factors for DFS in the T3-cent group. Multivariable analysis revealed that bronchoplastic procedures (p = 0.004) was an independent prognostic factor for DFS. CONCLUSIONS Survival for centrally located T3 NSCLC is better than other types of T3 NSCLC. Lung-preserving operations such as bronchoplastic procedures might result in improved survival of these patients.

Abstract
Background The optimal chemotherapy route for non-small cell lung cancers involving the phrenic nerve and diaphragm is unclear. The pharmacokinetic properties of paclitaxel following intravenous (IV) or intrapleural (IP) administration were analyzed in the plasma, lung, and diaphragm in a rat model. The purpose of this study was to determine whether IP injection increased paclitaxel concentration in the diaphragm. Methods Paclitaxel was administered by IV or IP to male Sprague-Dawley rats. The concentration of drug in the plasma, lung, and diaphragm was determined using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The pharmacokinetic parameters area under the curve (AUC), mean residence time (MRT), peak plasma concentration (Cmax), and half-life (t1/2) were analyzed. Results Paclitaxel concentration in the plasma, lung, and diaphragm decreased quickly following IV administration. However, after IP injection, paclitaxel reached a high concentration in the plasma, lung, and diaphragm that declined gradually. Significant differences in all parameters, except Cmax in the lung, were observed between the two routes of administration (all P < 0.05). Plasma exposure to paclitaxel IP was 41.1% of that observed after IV in the first 24 hours (P < 0.05). IP also significantly increased exposure of paclitaxel in comparison with IV administration to 267.3% and 905.7% of IV administration in the lung and diaphragm, respectively (P < 0.05). Conclusion These results suggest that IP administration may reduce systemic distribution of paclitaxel and increase the concentration in the lung and diaphragm. This could increase therapeutic efficacy by increasing the available drug and reduce systemic toxicity.

Abstract
Primary tumors of the diaphragm are rare. The most common benign cystic lesions of the diaphragm are bronchogenic or mesothelial cysts, while the most common benign solid lesion is a lipoma. Benign tumors of the diaphragm are resected if they are symptomatic or if there is a doubt about the diagnosis. The most common primary malignant lesion is rhabdomyosarcoma. Malignant tumors are treated based on histology and often with chemotherapy and/or radiation along with surgical resection if feasible. Endometriosis, a benign process that metastasizes to the diaphragm, is typically treated medically; surgical ablation or resection is considered only after failed conservative treatment. Surgical resection of metastatic malignant tumors, such as ovarian cancer and thymoma, as well as malignancies affecting the diaphragm by direct extension, such as mesothelioma, lung, and esophageal cancer, may provide some survival advantage.
